Hello Camaro folks, just wanted to do an update on the probs I was having last year with the rearend making moaning, ginding noises and had the fluid change done twice and the noise kept coming back. Well my dealership replaced the entire carrier unit in the diff on Janurary 5 and to date, knock on wood, NO MORE NOISES,,, and the rear now acts like a posi unit should. I am very happy with their work and my car. Good luck to any of you that are still having any issues..
